Slic3r STL Input

STL Sliced Import (by Slic3r). Supports OBJ/OFF/PLY/STL as input file formats. It requires OpenMesh:

Prepare to install openmesh

To run this extension you need to install OpenMesh bindings with python pip. When installing Paperfold by installing MighyScape, this will already be done for you on Linux systems. Else:

Ubuntu

sudo apt install cmake
sudo apt install g++
sudo apt install python3-dev
pip3 install openmesh

Fedora

sudo dnf install cmake
sudo dnf install g++
sudo dnf install python3-devel
pip3 install cmake
pip3 install pybind11
pip3 install openmesh

Windows

1. Windows requires CMake executable

2. Install MS Visual Studio Community Edition → If you receive an error like "NMake Makefiles does not support platform specification, but platform x64 was specified." In case the instalation fails you can also try to install precompiled Windows binaries from https://gitlab.vci.rwth-aachen.de:9000/OpenMesh/OpenMesh

3. Install openmesh bindings
   

   pip3 install openmesh

How it works

• projects an STL file on the X-Y plane by cutting the objects into "slices"
• each "slice" is a group of polygons, with a label indicating its z position
• the polygons are converted to paths for better editing in inkscape
• use Object → Rows & Columns →  distribute the slices in a grid

Warning: Requires Slicer 1.3.1-dev (the really latest build possible)
